Build a home for family in your garden in Sudbury

Bringing an elderly parent to live beside you in Sudbury often feels like the obvious answer, until you look at what the house can offer. A spare room up a flight of stairs rarely suits someone whose mobility is failing. A purpose-built single-storey home in the garden can.

We offer design and build of garden homes for family across Suffolk, with no steps to climb, a bedroom at ground level and a walk-in shower built in from day one. Planning goes through Babergh District Council, and we prepare and manage the application for you. Start with a free plot appraisal and we’ll tell you honestly whether your garden looks suitable.

How it plays out in Sudbury

How the two households will live together shapes the planning case as much as the drawings do. If your parent will eat with you, share the garden and rely on you day to day, an annexe is the natural fit, and that is what Babergh District Council will expect the application to describe. If your son or daughter will run their own home, pay their own bills and perhaps sell up one day, it is a separate dwelling and will be assessed against the council’s Local Plan as a new house. For a family in CO10, we help set that out clearly from the start.

Noon sun in Sudbury on 21 March sits about 38° above the horizon, so a typical two-storey eaves line (about 5 m) throws a shadow of roughly 6.4 m. In December the sun is only about 15° up and shadows stretch much further. Drawn for a garden facing north, where it matters most.

The next steps, locally

Getting started in Sudbury costs nothing. Send us a few photos of your garden and the way in, or simply call, and we’ll look at the plot from the desk and talk through your family’s plans. If there’s a realistic scheme, we arrange a site visit. Survey and design are quoted in writing before you commit, and the build price follows once the design is settled.

  1. Free plot appraisal

    We look at your plot, access and the planning picture from the desk, talk through who will live in the new home, and visit if it looks viable. There’s no cost and no obligation.

  2. Annexe or separate home

    We set out both routes for your plot, covering what each means for planning, ownership, council tax, CIL and VAT, so you can decide with your family and advisers before design starts.

  3. Survey and design

    A measured survey, then a design built around the person moving in: step-free routes, a ground-floor bedroom if needed and privacy for both households. You get a written quote after design and survey.

  4. Build and handover

    We build while you carry on living next door, with access, deliveries and working hours agreed up front. At handover you get the completion certificate and the paperwork you’ll need for council tax, lenders and any VAT claim.

Worth checking early

  • A separate home needs its own garden, parking, bins and access, so it needs more land than an annexe.
  • Family plans change: agree ownership, costs and what happens if circumstances change in writing, with a solicitor.
  • An annexe tied by planning condition usually can’t be sold or let separately, which limits flexibility later.

Your questions, answered for Sudbury

Can I build a separate house in my Sudbury garden for my son or daughter?

Possibly, if the plot can work as a home in its own right. Babergh District Council will look at access, parking, garden space for both houses, privacy and the character of the street, as it would for any new house. If permission is granted, the plot can be transferred to your child with its own title, with your lender’s consent if the house is mortgaged.

Will an annexe in Sudbury put up my council tax?

It might. Annexes can be banded separately, but exemptions exist for annexes lived in by certain dependent relatives, and in some cases a discount applies where family live there or the annexe is used as part of the main home. Who qualifies depends on the relative’s circumstances and how the annexe is used. Babergh District Council’s council tax team can tell you how the rules apply to your household.

Do I need planning permission for a granny annexe in Sudbury?

Yes, almost always for a detached annexe with its own kitchen, bathroom and bedroom. Babergh District Council will treat it as accommodation linked to your home and will usually add a condition so it can’t be let or sold separately. A garden building used only as a home office or gym is a different matter, but sleeping and cooking take it beyond those allowances.

How much garden do I need for a family home in Sudbury?

There’s no fixed figure. A single-storey annexe close to the house can work on a smaller plot than a separate dwelling, which needs its own garden, parking and access. What matters is whether Babergh District Council can be satisfied on privacy, daylight and the space left for both homes. The free appraisal gives you a first view based on your plot’s actual shape and access.
